[0021] In the description of this utility model, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. The various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0022] Example 1

[0023] Please see Figures 1 to 6 The present invention preferably provides the following technical solution: a finished cardboard stacking device, comprising: a frame 1; a transfer platform 4 disposed on the frame 1 for supporting cardboard stacks; and a clamping plate assembly disposed on the frame 1 for stacking cardboard; wherein the clamping plate assembly comprises base plates 2 fixed on both sides of the frame 1 respectively, and two first clamping plates 8 and two clamping plate components 7 disposed alternately on the frame 1 in a rectangular distribution; and further comprises a driving assembly disposed on the two base plates 2 for driving the two first clamping plates 8 and the two clamping plate components 7 to stack the cardboard stacks sequentially on the transfer platform 4.

[0024] Considering the issue of uneven stacking when stacking cartons, this embodiment includes a transfer platform 4 and a clamping plate assembly, which can be used for supporting the cardboard and aligning the stacks, respectively. Specifically, the two first clamping plates 8 and the two clamping plate components 7, where the clamping plate assembly is located, have an overall rectangular structure. Figure 1 , 2 As shown in Figure 5, the clamps can be held on the four sides of the cardboard to ensure the neatness of the cardboard stacking process. The driving component is designed to drive the two first clamping plates 8 and the two clamping plate components 7 to run sequentially. This reduces the adverse effects of the rectangular structure clamping the four sides of the cardboard at the same time. For example, if the corner of a skewed cardboard box exceeds the edge of the cardboard stack, and the rectangular structure clamps the four sides of the cardboard stack simultaneously, the friction between the cardboard boxes and the limitation of the stacking space may cause the corners or protrusions of the cardboard boxes to fold, resulting in damage to the cardboard boxes. Therefore, in this application, the two first clamping plates 8 and the two clamping plate components 7, which are rectangularly distributed, can be placed on the two opposite sides of the cardboard stack sequentially. This design ensures the neatness of the cardboard stacking while providing correction space for the alignment of the cardboard boxes, reducing the situation of skewed cardboard boxes folding and being damaged. It is worth noting that during the cardboard stacking process, the driving component can be adjusted once when a single cardboard box is stacked, or once every few cardboard boxes, or the whole box can be corrected after stacking. This method can be adjusted as needed.

[0025] Furthermore, the drive assembly is provided in two sets and distributed at both ends of the two base plates 2 and running relative to each other. Each drive assembly includes two transmission block assemblies 5. Each transmission block assembly 5 includes a guide rail 501, a first slider 502 slidably mounted on the guide rail 501, and a second slider 503 slidably mounted on the first slider 502 through a groove body opened on the upper wall of the first slider 502. The two first sliders 502 are fixed to the first clamping plate 8 on the same side, and the two second sliders 503 are respectively connected to the two clamping plate components 7. It also includes two sets of transmission rod assemblies 6, which are used to drive the first slider 502 and the second slider 503 where the two transmission block assemblies 5 are located to slide sequentially.

[0026] It is known, such as Figure 4 , 5 As shown in Figure 6, two sets of drive components are set at both ends of the two base plates 2 and run relative to each other. Each set of drive components includes two transmission block components 5, wherein the first slider 502 and the second slider 503 of each transmission block component 5 run back and forth. At the same time, the two first sliders 502 are fixed to the first clamping plate 8 on the same side, and the two second sliders 503 are connected to one end of the two clamping plate components 7. Therefore, when the first sliders 502 and the second sliders 503 are driven by the power provided by the transmission rod assembly 6 to drive the two first clamping plates 8 and the two clamping plate components 7 to abut against the side wall of the carton in a clamping manner, the stacking process of the carton can be completed, thereby providing convenience for subsequent packaging.

[0027] Furthermore, each transmission rod assembly 6 includes a motor 601 disposed on the side wall of the substrate 2, a drive rod 602 fixed to the output end of the motor 601, and a connecting rod 603, with a first pin rotatably connected at one-third of the upper part of the connecting rod 603. One end of the pin is rotatably connected to the end of the drive rod 602 away from the motor 601, and the other end of the pin is rotatably connected to a first transmission rod 605. The first transmission rod 605 is rotatably connected to the first slider 502 on the same side via a first rotating shaft. The assembly also includes a second transmission rod 606 and a third transmission rod 604 distributed vertically. One end of the second transmission rod 606 and the third transmission rod 604 are rotatably connected to both ends of the connecting rod 603 via a second pin, and the other ends of the two rods are rotatably connected to the connecting rod 603 and the substrate 2 on the same side via a second rotating shaft.

[0028] Combination Figure 4 , 5As shown in Figures 6 and 6, the third transmission rod 604, the first transmission rod 605, and the second transmission rod 606 are respectively positioned at the lower, middle, and upper positions of the connecting rod 603. Specifically, the first transmission rod 605 is positioned at the upper third of the connecting rod 603 and is connected to the drive rod 602 and the motor 601 via the first pin. The third transmission rod 604, the first transmission rod 605, and the second transmission rod 606 are rotatably connected to the base plate 2, the first slider 502, and the second slider 503, respectively. Therefore, when the motor 601 drives the drive rod 602 to rotate circumferentially, due to the design of the installation positions of the first transmission rod 605 and the second transmission rod 606, there is a certain displacement difference and speed difference between them, so that the first transmission rod 605 moves before the second transmission rod 606, thereby realizing the sequential clamping process of the two first clamping plates 8 and the two clamping plate components 7.

[0029] Furthermore, each clamping plate component 7 includes a telescopic column 701 installed in the middle of the base plate 2, wherein one end of the telescopic column 701 extends between the two first clamping plates 8 and is fixed to the second clamping plate 702, and the other end is fixed to the connecting block 703, and a spring 704 is disposed on the outer wall of the telescopic column 701 between the connecting block 703 and the base plate 2 for resetting the telescopic column 701; it also includes a wedge block transmission assembly, which is disposed between the second clamping plate 702 and the second slider 503 where the side transmission block assembly 5 is located.

[0030] Here, the two second clamping plates 702 and the two first clamping plates 8 form a rectangular clamping structure. The two second clamping plates 702 can be connected to the second slider 503 through the wedge block transmission assembly. Therefore, the first slider 502 drives the two first clamping plates 8 to move closer to each other, and the second slider 503 drives the second clamping plates 702 to move closer to each other, which can provide operating space for straightening the carton.

[0031] Furthermore, the wedge block transmission assembly includes a first wedge block 705 fixed to the side wall of the clamping plate component 7, and a second wedge block 706 that is in contact with the inclined surface of the first wedge block 705, and the second wedge block 706 is fixedly connected to the second slider 503 of the side transmission block assembly 5 via a connecting rod 707.

[0032] When the second slider 503 performs Figure 6 When moving horizontally as shown, the two second clamping plates 702 can be clamped towards each other by pushing the first wedge 705.

[0033] Example 2

[0034] As another embodiment of the present invention, the transfer platform 4 includes a base plate 401 fixed to the lower part of the frame 1, and an mounting plate 402 slidably installed with a groove opened on the base plate 401. A plurality of electric telescopic rods 403 are provided on the mounting plate 402, and the support plate 404 at the telescopic end of the rod is adapted to be connected with the opening groove 3 opened on the top of the frame 1 and used for supporting the cardboard.

[0035] Here, the base plate 401 and the mounting plate 402 are slidably installed together. Figure 4 , 5 As shown, the support plate 404 is adapted to be connected to the opening slot 3 on the top of the frame 1, and its height is adjusted by several electric telescopic rods 403 on the mounting plate 402. Therefore, after the carton stack is aligned, the electric telescopic rods 403 move down, and the sliding of the mounting plate 402 realizes the transfer and extension process of the carton stack. It is worth noting that a damper is installed between the mounting plate 402 and the slide of the bottom plate 401.

[0036] Furthermore, the support plate 404 has several through slots to allow workers to pack the cardboard stacks on the support plate 404.

[0037] Example 3

[0038] In another embodiment of this utility model, the upper surface of the two second clamping plates 702 is also provided with longitudinally arranged ruler strips 9 to indicate the thickness of the carton stack; and a laser emitter and a laser receiver are respectively arranged on the side wall near the bottom of the two ruler strips 9.

[0039] Combination Figure 4 , 6 As shown, in order to facilitate the measurement of the thickness of the cardboard stack, the scale strips 9 set on the two second clamping plates 702 respectively can realize the observation and adjustment of the cardboard thickness. It is worth noting that the scale of the scale strip 9 increases from top to bottom, and the second clamping plate 702 does not have a height limit for the area where the scale strip 9 is not set. This design facilitates the measurement of the thickness of the cardboard stack through the movement characteristics of the scale strip 9, and further converts the number of cardboard boxes, avoiding the cardboard stack covering the traditional scale to measure the thickness of the cardboard stack.

[0040] In the overall stacking mode of the selected device, the thickness of the carton can be used in conjunction with the laser transmitter and laser receiver. After the thickness of the carton stack is adjusted by 9, if the carton exceeds the laser transmitter and laser receiver and the two are disconnected, the laser transmitter and laser receiver will send a signal to the microcontroller. The microcontroller will drive the motor 601 and the electric telescopic rod 403 in sequence according to the steps to complete the adjustment during carton stacking and the transfer after stacking.

[0041] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "fixation" and other terms should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral part. There are various ways to install detachably, such as by using a plug-in and snap-fit ​​method, or by using a bolt connection, etc.

[0042] The above description of the specific embodiments of this utility model is only used to further illustrate this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-essential improvements and adjustments made to this utility model by technical engineers based on the above description of the utility model shall fall within the scope of protection of this utility model.
